- um@ Sm-ES The first l. case for a cartridge,'the"body of which is `aMTE-imi. rares vsfrurnun'w. woon', or conNwALL, .New v onirl' To allwhom 'may concern;

Be it known that l, STEPHEN W ..WooD, of

. Cornwall, county of Oran ge', and State of N ew York, have inventednew and useful Improvements in Cases for Gartrid ges; andi do herebydeclare that the followingis a full, clear, and

represent the improvements in they various stages of the process ofmanufacture.

'My invention relates to acase fora eartridge composed of a removable"and adjustable base or head, so constructed that it (the head) may beused separately upon different.

bodies.

partk of my invention consists in a cylindrical tube'folded over atoneend, and a wad having a central opening with a screwthread formedtherein to receive acorresponding screw projecting inwardly and.centrallyfrom the Vindependent removable and adjustable cup-shaped head,substantially as herein set `forth; also, in a .c ase for a. cartridge,of folding over one end of a re-enforce, and c ouning this folded endbetween twowad's, substantially in the manner herein described;

also, in a case for a cartridge, of a disk ofy metal, or other suitablematerial, on the inte'- rior of the body, composed of librous material,

substantially in the manner and for the pur- -pose herein set forth;also, ina case for a 'cartridge, of reducing a portion ofthe frontforopen end thereof, andtitting a re-enforce thereto, substantially in themanner herein set forth; also, in a case for a cartridge, of'acap-ejector to expelthe exploded cap -from the nipple or an- Vil,constructed substantially in the manner herein described. -1 j Likeletters indicate corresponding .parts in all of the figures.

. -A inthe accompanying drawings represents the body of acartridge-case, which is composed of any suitablematerial, and 1n thecommencement of the process of manufacture is a simple cylinder, asrepresented in Fig. 1, open at both ends, and of equal diameter. Theseveral other parts required to complete the body of a case for acartridge of this description iM'PRQvaM-ENTIN CARTRIDGE-cesesspecification fdr'ming part o'f Len-.emparent No. rasees, catena-une f3,revel,- appncatien filed "'.November15,l87 5. -i

consist of the interior reienforce B and wad C, as represented indetached Figs 2 and 3, and a removable and adjustable cup-shaped head,

After having prepared the cylindrical body A of` this case, vaportion ofoneend thereof is reduced in diameter, and folded over, as 'representedin Fig. 5, and the reenforce B, which is also reduced (or .mayhefredufc'ed therewith at' the same time) to correspond, is placed withiuthe. body A, and the wad C placedwit'hin the reenfox"ce,^asalsoshown in Fig. 5 when v the several parts thus prepared are dually'compressed. tightly together with punch and die, in the usual manner,asshown' in Fig. 6.'

To moreperl'ectly form the female screw in the wad o, Aal male screwis'placed within 'the blank-opening a, Fig. 5, before the lwad is com-4pressed, and .in the process of compressing and hardening it. the femalescrew e is' formed by forcing the wad around and againstv the malescrew, thereby taking form the saine as though' the thread were cuttherein in the ilsualmannenbytap, after the wad has been compressed.

To cut a screw-thread in a wad of iibrous material with a tap isdifficult, and vwhen so cutis liable to be ragged and imperfect; hencetheforming of the screw-thread thereinby compression.

Having proceeded thus far in the process of making fthebody 'of acartridge-case, having folded a portion of the end, and reduced andshaped the exterior, compressed the wad, and

formed the screw-thread therein,.a disk, o, of paper or othersuitablematerial, is placed 'over .the opening a, on theinterior surface of thewad, to prevent the powder escaping from the bodyjA-before the head vPis placed thereon.

An exterior cover, d, ,may` also be placed upon the outer end ot'the-case, which, though not absolutely necessary, would add' torthcprotection of the body, and inore'ueatly finish the whole.

vIn loading a casefor a cartridge, whe'thl r itbe with shot and wad orbullet and wad, the tendency, when forcing either the wad or bullet intothe end of the case, .is to expand it laterally; and as av case shouldtit'the cham.-

ber of the arm in `which it is to be used, the

' from the chamber slightest enlargement prevents the insertion of thecartridge into lthe chamber. Therefore,

'to prevent such enlargement of the frontend fthe case, a re-en force,F, is placed over or around the front'open end, as represented inr Fig.11.

Having completed the bodyAv for the rei ceptiou of the head P,.I willproceed to deL One form of this head P is' `Ais'i'rmly retained withinthis cup-shaped head when the cartridge is being fired; and tofacilitate theremoval of the head P from the body A after .the chargehas been fired, and

to more readilyplace the head upon a newv case or body, thecentrally-projecting screw to is made conical, as represented intheseveral figures. O n the exterior of the head P, and directly oppositethe inwardly-prqjectin g screw w,'is ananvil or'nipple, r, of anydesired form, upon which to explodethe percussion-cap to discharge thegunp'owder inthe body A, the flame of thel fulminate passing through theFig. 7 represents' central'longitudinal sec-v tion of a case for acartridge complete, conhead1?, and inside disk o. In cartridges of largecaliber, 'suchaslmay be required in cannoli or Gatling uns, ametal disk,B,'1nay be employed iu .th base of the body, tllroughwhich the screwwon; the head4 I? lmay pass iuentering' the wad, and taking into ascrew-thread formed in the center thereof, t0 assist in withdrawing theemptyl case of the `gun afterithe dis- .chargel l 5- .n.f Y

To give. addition al strength to" the' case A, to provide still furtheragainst the i-escapeof gas and the-destruction ofthebody,the` in.terijorl re -enf'orce B is folded over atone end,

and this folded' end placedbetweenvtwo wads',"

and the whole firmly swaged into theibase of I. 4 the body A, asrepresented in Fig. 9.

' In Fig. 10 the interior re-enforce B is. folded oven-and extends. theentire length of the body A, the two corresponding in generalconfiguration. A

Having completed the construction ofthe several parts of .the case, andVadapted each: tothe other, so that they may be'united into and form aperfect cartridge-case, and so constructed the-head that it may belremoved lfrom an exploded case, and readily 'adjusted to a new body tobe fired, it is.found necesejecting-rod, b, fitted loosely into thechannel :0, Fig. 12, formedtherei'n, leaving suiicicnt `space aroundlthe ejector-rod to allow the flame of the fulminate from thepercussionfcap topass into the body of the case to explode thepowde'rtlierein. Y

--To prevent the ejector-rod from falling out in the'act of ejectinganexploded cap from case for a cartridge, what I claim therein asnew,

isl

1. A case for a cartridge, consisting of a cylindrical body folded overat one end, a wad having a central opening, with a screw-thread formedtherein, and a cup-shapedhead having an inwardly and centrallyprojecting screw, the whole constructed substantially asherein setforth. v 2. In acase for-"a cartridge, an interior reenforce, one end ofwhich' is folded over and. confined between two wads, substantiallyy asdescribed. 3. In a case for a cartridge, ad'isk of metal and desire tosecure by Letters Patent,

or'other like suitable material, in combination' with an interiorfibrous wad or wads, substantially as herein specified.l Y

4. A case for a cartridge, having a portion of the front or open endreduced andre-en forced, .substantially in the manner herein described.

j 5. In a case, for a cartridge, a. stationary',` lnipple or anvilprovided with au .ejecting-rod, 'constructed and operatin gsubstantially as d'estantiallyas herein `set forth.

" 1. In the manufacture of cartridge-cases of f 'Y paper'or othersuitable fibrous material, the

process, substantially as herein described, of

lforming. the female screw-thread in the base thereof, for .thereception of the male screw screw-threadedmandrel inthe opening, and

"compressing the -wad or base' of the case around it, as set forth.
